Suspenison Bearing Lubricating System

ABSTRACT

Disclosed is a Suspension Bearing Lubricating System, lubricating moving parts engaging with pivoting suspension component bearings used in street motorcycles, dirt bikes, all-terrain vehicles and various other machines. The Suspension Bearing Lubricating System comprises of a bolt hollowed internally and capped with a grease fitting (or form of lubrication receptacle) or a bolt which is hollow at both ends but solid in the center and a specialized bushing allowing for the flow of grease. Lubricant will be inserted via a lubricant receptacle; lubricant will travel into the bolt then out of holes in the shaft of the bolt which will allow passage of lubricant into bushing if applicable. Once lubricant reaches specialized bushing it will travel into integrated grooves to holes in the bushing then out, directly in contact with the suspension component bearings.

DESCRIPTION

Field of Invention

The present invention relates to a Suspension Bearing Lubricating Systemwhich is able to internally grease surrounding bearings via specializedbushing (when applicable).

Background of the Invention

A suspension assembly composed of a (but not limited to) swing arm,shock and linkage assembly is commonly utilized in street motorcycles,dirt bikes, all-terrain vehicles and various other machines. Themovement and proper function of the suspension assembly is crucial tothe overall performance of said machine. These parts experience a lot ofwear due to friction, water, dirt, sand and other contaminates gettinginside the suspension component's bearings and/or bushings andshortening the life of the bearings. Proper and thorough lubrication ofthe swing arm and suspension linkage bearings can help slow and reducesuch wear. Over a period of time without lubrication the suspensionbearings will become filled with contaminants, oxidize, and seizecausing the machine's handling capabilities and performance to decrease.The decrease in suspension handling capabilities and performance canlead to (but is not limited to) malfunction, crashes, property damage,injury and death.

However, the assemblies must be easily accessible for lubrication andthe lubrication must cover a substantial portion of the surface area ofthe swing arm and linkage bearings to properly lubricate them. Regularsuspension bolts are not able to provide grease to the bushings tolubricate the suspension component bearings. The said bearings aredifficult to lubricate, due to the fact the user must partiallydisassemble the machine. The process of removing suspension componentsto properly and periodically grease the suspension bearings is a timeconsuming and vigorous process, generally causing the user to neglectthe bearings of proper maintenance and lubrication.

Presently, there is no publicly available form of a Suspension BearingLubricating System intended for street motorcycles, dirt bikes,all-terrain vehicles and various other machines capable of lubricating amachine's suspension bearings without some disassembly of the machine'ssuspension components.

BRIEF SUMMARY OF THE INVENTION

The Suspension Bearing Lubricating System has many aspects to make itwork properly for the application it is intended. Previously, tolubricate the suspension bearings of street motorcycles, dirt bikes,all-terrain vehicles and various other machines one had to partiallydisassemble the machine. Lubricant applied via a grease gun or some formof lubricating tool, will be able to travel from grease zerks orlubricant receptacle fitted at one or both ends of the bolt (dependingon the machine's specific application requirements) into the bolt'shollowed, internal passageway. Once the lubricant fills the passageway,the excess lubricant will flow into a specialized bushing surroundingthe bolt shaft (when applicable). The bushing will be suited with agroove inside the bushing which will allow lubricant to travelthroughout the entire bushing and eventually reaching the passage holesin the bushing. The lubricant will then travel from the through holesdirectly into the suspension bearings, internally lubricating them andpushing water, dirt, sand and other contaminates out of the bearingessentially preventing the contaminates from wearing the bearings and orcausing them to rust.

When the user uses the Suspension Bearing Lubricating System he/she willonly be required to connect a grease gun or lubricant provider to thegrease zerk or lubricant receptacle and insert grease or lubricant. Oncethe lubricant enters via the grease zerk or lubricant receptacle andtravels to the bearings, there is no more work needed to be completed bythe user. This simplistic maintenance allows the user to quickly andefficiently lubricant the suspension bearings preventing premature wear.

DETAILED DESCRIPTION OF THE INVENTION

Shown in FIG. 1 is the complete Suspension Bearing Lubricating System.FIG. 2 shows lubricant receptacles 5 secured to the threads 7 of FIG. 3.Lubricant will enter the lubricant receptacles 5 until it fills thepassageway(s) 6 shown in FIG. 3 in the shaft 1 of the bolt. Once thelubricant fills and forces itself out of the passageway(s) 6, it flowsfrom the holes 4 shown in FIG. 2. The lubricant will flow from the holes4 into the specialized bushing's grooves 10 shown in FIG. 5. Thelubricant will travel along the lubricant guide grooves 10 to the exitholes 9 of the specialized bushing(s) shown in FIG. 5. Once thelubricant reaches the exit holes 9, it will flow directly into thesuspension component's bearings. Thus, lubricating them and preventingthem from premature wear and failure.

The round bar stock is cut to desired length then placed in a CNCmachine and turned down until given the appropriate circumference of thebolt head 2 then again to reach the circumference of the bolt shaft 1.The threads of the bolt 3 will then be machined into the end of theshaft 1. The bolt will then have passageway(s) 6 drilled into the centerof the ends of the bolt. Next the holes 4 appearing in FIG. 2 aredrilled into the shaft 1. Once the holes 4 are in place, the lubricantreceptacle threads 7 will be tapped in each lubricant passageway 6. Thespecialized bushing 8 will be made from pipe pre-cut to desired diameterthen cut to desired length. The lubricant guide grooves 10 are machinedinto the inside of the specialized bushing 8 with a CNC machine. Lastlythe specialized bushing's lubricant exit holes 9 will be drilled outcompletely. This completes the manufacturing process of the SuspensionBearing Lubricating System.

In the above-presented embodiment examples, the lubrication system wasinstalled in a dirt bike equipped with a pivoting swing arm and linkagesuspension assembly, where it secures the swing arm, shock, and alinkage assembly. The lubrication system is also suitable for othermachines equipped with a pivoting swing arm and linkage assembly, oralso such other working machines that have a suspension assemblyrequiring continuous or intermittent lubrication during the operation ofsaid working machine. Consequently, the present disclosure is notlimited to the embodiment examples presented above, but it may varywithin the scope of the appended claims.
